Pulmonalarterie - Relaxation
Figure 1: Relaxation of bovine pulmonary arteries under basal conditions. A: Representative tracing. Endothelium deprived artery strip (detector) was precontracted with 10-5 M histamine (HA). In the upper panel significant relaxation was induced by perfusing the detector with effluent of an endothelium intact pulmonary artery (generator) which was collected and stored prior to perfusion for five minutes (CE). Following direct superfusion (G), additional relaxation was induced. In control experiments (lower panel) only direct superfusion (G) was performed; W = wash. B: Average relaxation. Data shown as mean +/- SEM.

Pulmonalarterie - Relaxation
Figure 2: Relaxation of bovine pulmonary arteries under stimulated conditions. A: Representative tracing. In the upper panel significant relaxation was induced by perfusing the detector with effluent of an endothelium intact pulmonary artery (generator) which was collected and stored prior to perfusion for five minutes (CE). Addition of acetylcholine (ACh 10-6 M) to the perfusion medium of the generator (CE-ACh) augmented relaxation. Following direct superfusion (G-ACh), relaxation was more pronounced. In control experiments (lower panel) only direct superfusion was performed; W = wash. B: Average relaxation.
